No matter how far it is to this planet it is still a foolish thought to try and go there.
The Earth is made up of a fixed amount of mass that determines the earths orbital distance from the sun. So to get to this other planet we would have to build a spaceship with a mass from the earth and then send it light years away to this other planet. OK So what happens to the earths mass. The earths new mass would be old mass minus the space ship mass. If you apply the universal equation F = (G x m1 x m2)/r and make m1 the sun and m2 the earth then if changing the mass of m2 (the earth) this has to change something else, F or r. The fact that it is light years away would mean anything that is sent there form earth would no longer interact with the whole earths mass. Ask yourself Do you want to destroy this earth planet and everyone on it in an attempt to find another one light years away?
